The remnants of pesticides in livestock feeds have been increased by excessive using of these pesticides so as to meet extreme demands for more feeds. Finding a new strategy for reducing pesticides negative effects is absolutely necessary. Therefore, evaluation of the effects of sodium bentonite on blood parameters, feed digestibility and rumen fermentation parameters in sheep fed diets contami...

The effect of inclusion of garlic essential oil (EO) at 33, 66 and 100 μg mL-1, raw garlic (GAR) at 5, 10 and 15 mg mL-1 and monensin (MON) at 7.5 μg mL-1 of incubation medium on organic matter digestibility (OMD) was studied with in vitro gas production, ANKOM daisyII and conventional in vitro (IVOMD) methods. The material was incubated with sheep ruminal fluid and the experimental design was ...

Forages are a necessary component of diets for lactating dairy cows because they provide coarse fiber needed to optimize rumen function. However, forages alone provide insufficient nutrients to achieve high milk yield, and they must be supplemented with other feed ingredients. Because forage quality is highly variable, their quality must be assessed before diets are formulated. Forages have bee...

A dual-flow continuous culture system consisting of 4 fermenters was used in a 4 x4 Latin square design. The objective of the research was to evaluate the effects of solid dilution rate (SDR), pH, and concentration of linoleic acid (LA) in the feed mixture on the production of conjugated linoleic acid (CLA) and trans-C18:1. The 4 treatments were 1) control = pH 6.5, 1% LA, 4%/h SDR; 2) high sol...

Understanding potential impacts of vegetation change on caribou energetics requires information on varia¬ tions in forage quality among different plant types and over time. We synthesized data on forage quality (nitrogen, neutral detergent fiber and dry matter digestibility) for 10 plant growth forms from existing scientific literature and from field research in the Arctic National Wildlife Ref...

This study examines the effect of physically effective Neutral Detergent Fiber (peNDF) value roughage on milk composition and yield. The NDF varies depending particle length amount structural non-structural carbohydrates in diet. quality, quantity, are crucial for a healthy rumen. longer is, more cow ruminates saliva it produces. produced is used to balance rumen pH. It aimed protect animal hea...

In order to determine of physical characteristics of rice straw as an effective source of fiber in ruminants, alfalfa hay, four varieties of rice straw (Taroum Neda, Taroum Neamat, Taroum Sangi, and Asgari), and four rations that contained four varieties of rice straws were investigated. The chemical (dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), nonfiber carbohydrates (N...

Seasonal changes in chemical composition represented by crude protein (CP), In vitro true digestibility (IVTD), and fibre components measured neutral detergent (NDF), acid-detergent (ADF) lignin were evaluated at specified cano­py ages stages of maturity Tridax procumb ens. Samples selected from five harvest dates April, June, August, October, December. Chemical com­position was: highly respons...

Twelve early lactation Holstein cows (4 fistulated) were used in replicated 4x4 Latin squares with 4-wk periods to determine the effective neutral detergent fiber (NDF) content of wet corn gluten feed and to measure the effect of forage particle size on ruminal mat consistency and passage rate of wet corn gluten feed. Diets were 1) 23.3% NDF (17.4 percentage units of NDF from alfalfa silage), 2...

Because grain is highly digestible, maize hybrids for silage production are generally chosen based on their The nutritive value of forage maize (Zea mays L.) may be improved grain yield. However, the stalk portion of the maize through genetic selection for increased rate of fiber digestion or decreased indigestible fiber concentration. To identify sources of genetic plant contains 50% or more o...
